Expected & Actual behavior (期望与实际表现)

I first randomly create a graph. Then when I run the following query: g.V().in('el2','el1').as('x').V().inE('el2').outV().where(within('x')) is thrown with an exception. I think this query is syntactically and semantically correct, but I keep triggering this kind of problem. The query generation rule can refer to: https://stackoverflow.com/questions/48067834/gremlin-intersection-operation.

• Expected behavior: No exception should be expected to throw.

• Actual behavior: A java.lang.ClassCastException is thrown. And I'm not really sure whether this problem should happen so I report this.

HugeGraph exception :
java.lang.ClassCastException: com.baidu.hugegraph.structure.HugeVertex cannot be cast to java.util.Collection
